In Office 365 I am using the workflow action Copy document from library, and it is failing with “Exception: Unknown Error”.
The file does get copied to the new library, but the action throws the error at some point in the process.
I have a variable set for retrieving the File ID of the newly copied file.
If I set ThrowError to “No” and then log the value of the File ID returned, the File ID is 0.
I have stripped down everything in the workflow to just this one action and even hard-coded the SourceURL and the DestinationURL to make it all as simple as possible, but I still get the error.
Thanks for your help.
